Analysis of deformation models based on sigmoidal vein arrays in the Bahlgerd shear zone

MohammadAmir Alimi

Volume 32, Issue 1 , March 2022, , Pages 89-102


  The Bahlgerd shear zone in the northern margin of Bagheran Mountain is separated Eocene flysch from the Cretaceous ophiolite sequence and Quaternary sediments by southern Birjand and Bahlgerd faults. In the deformation evaluation , sigmoidal array arrays located in sandstone units have been used as strain ...  Read More

  Hydrothermal vein and porphyry copper deposits are notable within Eocene volcanic rocks of Shahr-e-Babak area. In this paper, the structural patterns within Shahr-e-Babak area as well as the relationship between structural elements and the emplacement of dikes and hydrothermal vein and porphyry copper ...  Read More

Structural Evidences of Continental Transpression in the Birk Area(SE Iran)

E. Moosavi

Volume 20, Issue 79 , January 2011, , Pages 75-82


  Some structural evidences of continental transpression are studied and compared with experimental modeling results in the Birk area. These evidences are: fold axes have a double plunging en-echelon pattern. Fold axes mean orientations and fracture cleavages strike form angles less than 45 degrees with ...  Read More
